The Experimental Virtual Environment The Experimental Virtual Environment (EVE) is a project being conducted by the Helsinki University of Technology and the high-performance computing and networking center in Finland. The EVE encloses the user inside three walls and a floor that are rear projection screens, and the user can interact with the environment with a head tracking unit and other sensors. A brief introduction is given on the EVE Web site, followed by examples of applications for the system, its current implementation, andAuthor(s): Creator not set

The Virtual Terrain Project The Virtual Terrain Project (VTP) homepage has a wealth of information about three dimensional environment rendering, as well as links to many different research efforts and papers about the subject. The project's aim "is to foster the creation of tools for easily constructing any part of the real world in interactive, 3D digital form." Several subtopics are addressed, including plant modeling and realistic ground detailing and texturing. An interesting focus is on cultural aspects of terrain reAuthor(s): Creator not set

Examine the phases of the moon from Earth and space This animation is designed to help Earth science students correlate the moon's phases with its orbit around the Earth. The introduction explains that, while the sun always illuminates one half of the moon, the moon's appearance depends on how much of the sunlit moon is facing the Earth. The split-screen animation includes two views of the moon: one from Earth and the other of the moon's orbit around the Earth. Students may toggle between an oblique view of the earth-moon system and a view from aAuthor(s): TERC. Center for Earth and Space Science Education

Quick take on science-themed days and weeks This one-page document highlights websites that focus on science-themed days and weeks such as Earth Day, World Ocean Day, and Earth Science Week.Author(s): NSDL Middle School Portal

In this section we are going to review the different needs that drive the creation of corporate governance frameworks. The contingent model of regulation applies to financial reporting: the idea that equilibrium in regulation exists, but is broken by some intrusive event, often a financial scandal. This leads to a search for a revision of the rules, and a new equilibrium is worked out. This is very much a pattern that drives change in corporate governance.

Population Density: How Much Space Do You Have? Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and design as well as for resource allocation.Author(s): Integrated Teaching and Learning Program,

Just Plane Simple This lesson introduces students to three of the six simple machines used by many engineers. These machines include the inclined plane, the wedge and the screw. In general, engineers use the inclined plane to lift heavy loads, the wedge to cut materials apart, and the screw to convert rotational motion into linear movement. Furthermore, the mechanical advantage describes how easily each machine can do work and is determined by its physical dimensions.Author(s): Integrated Teaching and Learning Program,

Copycat Engineers This lesson introduces students to the idea of biomimicry — or looking to nature for engineering ideas. Biomimicry involves solving human problems by mimicking natural solutions, and it works well because the solutions exist naturally. There are numerous examples of useful applications of biomimicry, and in this lesson we look at a few fun examples.Author(s): Integrated Teaching and Learning Program,

Light vs. Heat Bulbs Students measure the light output and temperature (as a measure of heat output) for three types of light bulbs to identify why some light bulbs are more efficient (more light with less energy) than others.Author(s): Office of Educational Partnerships,

We’ve Come a Long Way, Baby! Students discuss several human reproductive technologies available today — pregnancy ultrasound, amniocentesis, in-vitro fertilization and labor anesthetics. They learn how each technology works, and that these are ways engineers have worked to improve the health of expecting mothers and babies.Author(s): Integrated Teaching and Learning Program,

Riding the Radio Waves Through this lesson students learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as identifying the amplitude and frequency of a given waveform. Students then learn general concepts about magnetic fields, leading into how radio waves are created and transmitted. Several demonstrations can be performed in order to help students better understand these concepts.Author(s): Techtronics Program,

Drifting Continents This activity is a teacher-led demonstration of continental drift and includes a math worksheet for students involving the calculation of continental drift over time. Students will understand what continental drift is, why it occurs, and how earthquakes occur because of it.Author(s): Integrated Teaching and Learning Program,
